Perhaps the use of std::string is needlessly limiting, but what makes the
property_tree a little bit different than a generic tree container is the
concept that child nodes are associated with a key, and there are
convenience methods provided for finding nodes by their "path" in the tree.

The same effect could perhaps be accomlished using (hypothetically) a
generic_tree<std::pair<std::string, std::string> >, but this would need to
in turn be wrapped in another interface to achieve the same ease-of-use.
